前記ビームフォーミング部および前記受信部を制御し、対応する送信ビームを通じて多数の基準信号を送信するように制御し、受信ノードから、前記基準信号に基づいて前記受信ノードにより生成された望ましい送信ビームを指示する情報を受信するように制御し、前記望ましい送信ビームを指示する情報に基づいて前記受信端への信号送信のための送信ビームとして第1送信ビームを決定し、前記第1送信ビームを用いて前記受信ノードに信号を送信するよう制御し、前記受信ノードからビーム変更要請を受信するように制御し、前記受信ノードへの信号送信のための送信ビームとして第2送信ビームを決定し、前記第2送信ビームを前記受信ノードへの信号送信のための送信ビームとして追加または変更する制御部を含む。
例えば、前記図3の場合、本発明は、送信ビーム-E325および受信ビーム-B332が最も大きな受信信号の強さを持つ望ましい送/受信ビームの対として選択されたことを仮定する。
前記表2に示すように、前記端末310は、受信ビーム-A331に対して送信ビーム-A321、送信ビーム-D324を好み、受信ビーム-B332に対して送信ビーム-C323、送信ビーム-E325、送信ビーム-F326を好み、受信ビーム-C333に対して送信ビーム-G327、送信ビーム-H328を好み、受信ビーム-F336に対して送信ビーム-F326が望ましい。ここで、前記端末310は、受信ビーム-D334、受信ビーム-E335に対してどのような送信ビームも好まない。
